what are some of the popular brake upgrades for the 996tt BESIDES the PCCB ?
please post pics
i would assume that the cayenne 6 POT BBK would be a logical choice
( i even have it on my Audi)

 

Steve depending upon your white size there are different kits out there. A 6piston EVO kit, a 6piston Brembo kit or even an 8-piston. There are street or race style kits as well.

 

alex, how do you feel about brembo GT-Rs?

 

I have the 6 piston Evo Big brake kit and couldn't be happier. I have tremendous braking power. The Brembo GT kits are equally amazing. You can't go wrong with any of the upgrades mentioned by Alex.

Anyone have any experience with the new 6 piston Brembo GTs? They have 380mm or 355mm discs for the 996TT and C4S, supposedly very light.

 

These are awesome and finally decided to go with them as did some of my other car guys.

All the above are good choices just depends on what you are looking for!

they come in red or yellow but say Brembo on them. you need to pay extra$ if you want them repainted and porsche put on them. I didnt bother the Brembo looks fine.

 

Did you change the rear brakes also, or just the front? I am intrigued.

 

Just for curiousity, why change to six piston? Seems to me that the "problem" with 996 turbo is the PSM causing the brake to work too hard, hence heat....that would happen to any other caliper and rotor assuming that your running race type rubber?

 

I would disagree that the same heat related problems would happen to "any other caliper and rotor".

Most upgrades for the 996TT only come as complete systems.
When you upgrade to a larger disc (the primary heat sink of a brake system) to be able to handle the extra heat, you need to make the appropriate changes to the caliper.

Larger discs help by increasing heat capacity and efficiency, but also increase the effective radius (leverage provided by the distance between the center of the disc and center of the pad). In order to remain within the appropriate range for optimum bias, you must reduce the piston area within the caliper.

So why six piston???

Since you will be changing the calipers anyways, why not select one that also provides the largest benefit for performance and efficiency.

Brembo's new 6-piston caliper has a very impressive pad design. While maintaining a short annulus pad (good for extending the effective radius), it also covers a large portion of the disc, providing increased pad volume and swept area. This adds to the life span of both the pads and rotors.

The 6-piston caliper (with the appropriate piston area) will also improve pedal feel and modulation, as well as prevent uneven pad wear or taper.

All of these characteristics add great benefit during normal and even spirited driving, as well as in race like conditions.


P.S. Comparison of Brembo 14" kit w/ 6-piston caliper
OEM caliper weighs 10.1lbs vs. Brembo caliper weighs 7.8lbs
OEM disc weighs 23.4lbs vs. Brembo disc weighs 16.9lbs

 

No for two reasons one the fronts do most of the work so the cost benefit ratio is not good and two you loose the parking brake function

 

Gary's answer was on spot. One of the main improvements is the increased size of the rotor to dissipate more heat and this is what decreases brake fade.
Secondly the brakes are not working any harder due to the PSM unless you are off line. Anyway at the track I dont run with the PSM on anyway.

hope this helps!

How much for what you have tom?

 

Question...

If you're running stage 1/2 (non X50) and want a cost effective upgrade for the brakes should I look to just changing the fronts ? If so what is the best upgrade for the fronts for a stage 1/2 daily driver ?

I don't track the car.

 

The warning light came on 1/2 hour ago, I've apparently worn my pads down to the sensors. Clearly I need these new Brembos.

I just purchased the Rotora 6 piston front / 4 piston rear with 355 mm slotted rotors...
the rotor is 17 lbs.
the 4 piston caliper with pads is 6 lbs.
the 6 piston front caliper with pads is 7 lbs...
I say thats pretty good.
